> Name clash compile error in the deprecated org.apache.hadoop.util.MemoryCalculatorPlugin
due to JLS3 8.4.8.3 (cf. http://bugs.sun.com/view_bug.do?bug_id=6182950)
> The bug doesn't manifest in jdk 1.6 up to 20, but shows up in NetBeans 6.9+ due to its
bundled (conforming) compiler. Fix is trivial: just remove the offending method in the deprecated
subclass as its equivalent erasure is inherited from the parent class anyway.
